Method

  1. 1

    Cube the butter and place it in the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with a hand mixer. Beat on medium-high speed for 3–4 minutes, scraping down the bowl once or twice, until the butter is noticeably paler and looks light and creamy.

  2. 2

    Reduce the speed to low. Add the icing sugar in three additions, beating each one in until just combined before adding the next — going slowly here keeps you from wearing the kitchen.

  3. 3

    Add the vanilla, salt, and one tablespoon of the milk. Beat on low until everything disappears into the buttercream, then turn the mixer up to medium-high and whip for a full 3 minutes. This is what takes the buttercream from grainy to silky, so do not skip it.

    Check the consistency. If the buttercream feels stiff, add the remaining milk a teaspoon at a time, beating between each addition. For piping, you want it thick enough to hold a peak but soft enough to push through a star tip without forearm cramp. For a smooth cake covering, aim slightly looser.

  5. 5

    Use straight away, or transfer to an airtight container. Press cling film directly onto the surface to stop a crust forming.

Baker's Notes

  • Cool room temperature butter is the make-or-break detail. If your butter is too soft (greasy, almost shiny) the buttercream will be soupy and never set up properly. Press the butter — your finger should leave a small dent without sinking in.
  • Sweetness control: this is the standard 1:2 butter-to-sugar ratio for a buttercream that holds up to piping. For a less sweet, softer-textured spread, drop the icing sugar to 400g.
  • Yield: covers and fills a 20cm two-layer cake, or pipes generously onto 12 cupcakes. Use the buttercream calculator on cakeytops.co.uk if you are scaling up for a tiered cake.
  • Storage: airtight at room temperature for up to 3 days, in the fridge for up to 2 weeks, or frozen for 3 months. Bring back to room temperature and re-whip for 1–2 minutes before using.
  • Colouring: use gel or paste colours rather than liquid — liquid food colour will thin the buttercream and dull the colour. For deep reds and blacks, colour the buttercream the day before so the shade can deepen overnight.
